What is the fundamental cause of periodicity observed in physical and chemical properties of an atom?
The periodicity observed in physical and chemical properties of an atom is primarily due to the arrangement of electrons in energy levels or shells around the nucleus. The periodic table organizes elements based on their atomic number, which corresponds to the number of protons in the nucleus. This arrangement influences the elements' electronic structure and, consequently, their properties.
Why do isotope have the same chemical properties?
Isotopes of an element have the same number of protons, which determines the element's chemical properties. The differing number of neutrons in isotopes does not significantly affect the element's chemical behavior.
What is Periodicity best defined as in chemistry?
Periodicity in chemistry refers to the repeating patterns of properties of elements on the periodic table based on their atomic number. This periodic trend helps in predicting the physical and chemical properties of elements and their compounds. The concept is essential for understanding the behavior of elements and the organization of the periodic table.
What is true about the number of protons and nuetrons in an isotope?
Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.
What 2 properties are the modern periodic tables based on?
It is based on atomic number. The number of protons.
How is the periodicity of properties dependent upon the number of protons in an atom?
The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.
How the periodicity of properties dependent upon the number of protons in an atom?
The number of protons is equal to atomic number. The periodicity of chemical properties depends on the outermost shell of electrons.
What two properties are the modern periodic table based on?
Properties of elements are periodic function of atomic number. Elements with same chemical properties are grouped together.
Who is the scientist mosley?
in 1914 Henry mosely stated the modern periodic law. He said that when the elements are in order of increasing atomic number (number of protons) they show a periodicity or repeating pattern of properties.

Why modern periodicity consist the protons of any atom?
In the periodic table chemical elements ar listed after the number of protons in the atomic nucleus.
Why do isotope have the same chemical properties?
Isotopes of an element have the same number of protons, which determines the element's chemical properties. The differing number of neutrons in isotopes does not significantly affect the element's chemical behavior.
Why do all isotopes of an element have the same cheimcal properties?
The chemical properties of an element depend on its electron configuration, which is in turn determined by the number of protons. Isotopes of an element differ in the number of neutrons, which, being neutral, have not influence on chemical properties.
What is the basis for the arrangement of elements in the periodic table?
The short answer is order. Elements are grouped in a table according to similarities in electron structure, atomic composition, the number of protons / neutrons / electrons. This also then naturally groups them by similar properties, metallic / nonmetallic, electronegativity, etc. Periods (columns) group by number of valence (outer shell) electrons.the basis of arrangement of element in a periodic table is based on the increasing proton number of the elements.
What is Periodicity best defined as in chemistry?
Periodicity in chemistry refers to the repeating patterns of properties of elements on the periodic table based on their atomic number. This periodic trend helps in predicting the physical and chemical properties of elements and their compounds. The concept is essential for understanding the behavior of elements and the organization of the periodic table.
Periodicity is best defined as?
The repitation of physical and chemical properties of elements periodically is called periodicity
What is true about the number of protons and nuetrons in an isotope?
Isotopes of an element have same number of protons and different number of neutrons. Hence similar in chemical properties and different in physical properties.
